I quit smoking cigarettes 5 years ago, I then started immediately not spending USD$200 a month. Three years ago I started spending that amount on bitcoin. I am dollar cost averaging, I don't get upset about large or small swings.
I've tried to play it a few times, ran a bot on Gox that did very well. Since Gox went away I just hodl. Even if bitcoin goes to zero, I spent the $$$ in something I believe in, instead of sending it up in smoke, and killing myself.
wow a good job for you buddy removing vices would be a good decision to save money, investing it to something that will benefits you in the long run like bitcoin will profits you just needed to wait an see the results. good luck to you and keep it up mate.
